Wheelchair Ramp Problem (doc | pdf)

A company that makes wheelchair ramps needs to revise their catalogue to include the steepness of each ramp. Your company was given a subcontract to do this work. Within the current catalogue of wheelchair ramps, there are 8 models. You need to determine the steepness of each ramp and order them from least steep to most steep in the catalogue.



Here is your task:

  • Compare each pair of ramps.
  • Make an ordered list using all models (1-8), from least steep to most steep.
  • Provide a mathematical justification for how you ordered your list.
  • Describe any patterns you notice in the data.
